finally broke down a bought the 50ppm CYA standard. wasnt having problems just wanted to know that i was getting close to my target level and wanted to calibrate my eye. So i recieved the standard and have not been able to get any results with it. It is crystal clear at 50 ppm and even when i fill the test tube all the way up to the top i can still see the black dot crystal clear. So I began to think that maybe it is made so that it resembles 50ppm CYA in regular water and that i still had to add the CYA test reagent to it and then do the test, then it was so cloudy that i couldnt see the black dot with only a couple drops in the tube showing over 100ppm. Any thoughts?
